The brake pedal on our 1994 Suburban has suddenly gone to the floor with very little stopping power in the brakes. All brakes look dry, and the master cylinder has plenty of fluid. I have replaced the master cylinder and if the engine is not running, the brake pedal feels normal, but the moment the engine is started, the brake pedal goes to the floor again.
What type of brake system do you have? Vacuum or hydraulic assist?
You definitely need to bleed the breaks
How to Bleed your Brakes by Yourself
SOURCE: 1994 ford explorer will not stop, I have replaced the brake pads,
I could be your brake booster which provides the power assist in your braking. The hissing would indicate a booster gone bad. With no booster it takes a lot of pedal pressure to get the braking you are used to.

do u have the antilock brake bleeding tool? if not you will need to have the dealer bleed the brakes, the ABS control valve must be electricaly held open to bleed the brakes there of course is a special tool for this.
